I'm currently a emergency room scribe at one of the hospitals in my area. I basically follow around ER physicians and document patient medical records/procedures/discharge papers.
It's honestly just a stepping stone for me right now since I'll be in medical school pretty soon.

Biology Teacher: BABYSITTING teenagers. Getting them to line up, sit quietly, don't play with phones/laptops, don't read porn... all of this takes up the 1 hour slot already. I don't actually get to teach Biology. No, I'm just exaggerating.

Hospital Scientist: Looking at people's brainwaves and determining whether they have sleeping disorders.
